Synthesis |
Procaterol, 5-[1-hydroxy-2-[(1-methylethyl)amino]butyl]-8-hydroxy-2-(1H) quinolone (23.3.25), is synthesized by acylation of 8-hydroxy-2(1H)-quinolone with 2-bromobutyric acid chloride at the fifth position of the quinoline system, which gives the compound 23.3.23. This undergoes action of isopropylamine, forming an aminoketone 23.3.24, the carbonyl group of which is reduced by sodium borohydride, giving procaterol (23.3.25) . |
